Well, I think there was some more wrinkles to the Lenin quote and that's pretty hilarious that Keynes is considered to be the grandfather of modern state finance and he essentially said that it was communism. The Communist Manifesto states that a central bank is one of the 10 planks also.
Money is designed to empower the users, so it's quite moot. Sneaking it across borders is why compact is one of the features that defines monies.
In the initial setup of socialist states, there was no real concept of bank wires. The modern socialism is using this to eliminate money (as in portable cash) by licensure over the banks, who must comply with the company policy, I mean statutes. In this way they hope to be able to use the money as a control system rather than lubricant and communication system for production.
We all know where this central control ends up though, no amount of new gadgets and doodads is going to change the result.
